As a raiding priest (when I'm not multiboxing) I'd take issue with those choices.

If I'm healing a tank and his health is very low (say < 25%) and falling fast, I'd *not* use Greater Heal, simply because it takes too long to cast. Same for Prayer Of Healing.

Greater Heal is the heal of choice if you have the time to use it because it's the most mana efficient (same for Prayer of Healing for group use), but you don't want to be using it if there's any chance your target could die while you're casting, so you need to use the shorter cast-time spells.

I understand you're trying to simplify what is, in reality, probably the most complex role in WoW, and so compromises need to be made, but this is roughly how my brain works when healing:

Tank/Plate target:
- low health (<25%) and losing health quickly = Flash Heal (maybe preceded by a shield or Prayer of Mending)
- low health and not losing health quickly or doesn't have aggro = Greater Heal, Prayer of Mending
- medium health (25% - 90%) = Greather Heal, Prayer of Mending
- high health (>90%) = Renew

Squishy target:
- low to medium health and has aggro = Flash Heal (maybe preceded by a shield or Prayer of Mending)
- low to medium health, doesn't have aggro = Greater Heal
- high health = Renew

Group:
- average low health, someone very low health = Circle of Healing
- average medium health = Prayer Of Healing
- average medium to high health = Renew on all

The group healing choice is made a bit more complicated in the next patch, when CoH gains a 6sec CD...
